.To all whom t may concern:

Be it known that I, ALEXANDER CHRISTIE, citizen of the United States,residing at Seattle, in the county of King and State of Vashington, haveinvented a certain new and useful Improvement in Hasp-Fasteners, ofwhich the following is a specification.

My invention relates to hasp fasteners for doors, and the object ofmyinventionv is to l rovide a hasp fastener which shall be-r adapted to beassociated with a single door and its door frame, or to be associatedwith a pair of doors disposed in a' single door frame there to operatereleasably and rigidly to lock .said door or said doors in a closedposition. A further object of my invention is to provide a hasp fastenersok constructed that it will be particularly adapted to be associatedwith a pair of doors that is employed to close the rear entrance to acovered delivery'wagon, such as is employed by mercantile houses fordelivery of merchandise, whereby said pair of doors may be releasablyheld in such tightly closed position as will effectively prevent arattling or vibral tion of the doors of said pair irrespective of any,wearv of the parts of said hasp fastener.

I accomplish .these objects by devices illustrated inthe accompanying`drawings wherein Figure 1 is a view in front elevation of a haspfastener embodying my invention; Fig. 2` is a view in longitudinalsection on broken line 2, 2 of Fig. 1, showing the same associated witha pair of doors. in their closed positions;

v Fig. 3 is a fragmentary view in front elevation of parts ofthe same,showing one part in vertical cross-section on broken line 3, 3 of Fig.2; l

Fig. 4 is a planrview of the same, in association with a pair of doors,showing relative operative positions of the parts thereof; and f Fig. 5is a fragmentary plan view of the same showing a modified arrangement ofits parts.

Referring to the drawings, throughout which like reference numeralsdesignate like parts, 5 and 6 represent a pair of doors which may behinged at their outer side edges and adapted to close as illustrated inFigs. 2 and 4, against any suitable stop, as a door frame or stud 7.

A spring-like bar 8 of suitable metal, as

spring steel, is slightly curved to dispose its two end portionsnormally in planes that areat a slight angle to each other, as shown inFigs. 2 and 4, one of said end portions being providedv with holes 9, 10:and 11, as indicated by dotted circular lines in Fig. 3, through whichholes 9. 1() and 11 extend bolts, as bolts 13, whereby said springlikeb'ar'S may be bolted to a door, as the door 5 in the manner shown inFig.

Secured to the bar 8, between the heads of two of the bolts 13 and 14and its outer side surface, is the base of a catch'12, of the form shownin Fig. 2. y

Bolted to the front side of the door 6, by bolts 14, is a bracket 15 towhich is hinged one end of a straight latch bar 1G that is adapted toengage its inner'side surface, at avpoint near its hinged end, with theoutwardly curved end portion of the bar 8 when it is actuated to swingto the position parallel with the front surfaces of thedoors 5 and 6, asshown in Fig. 2, whereby said end portion ofthe bar 8. will be pressedtoward the door 6 and whereby the spring-like action of said bar willtend to press the latch bar 16 outwardly from its said parallel positionadjacent to the doors 5 and 6. y

' Extending'through the latch bar 16, near its free end, is a slottedhole 17 through which ther catch 12 may project outwardly when saidlatch bar 16 is pressed toward the door 5to its position shown in Fig.2; and the outwardly projecting portion of said catch 12 is providedwith a hole 18 in which the loop of a padflock may be disposed, if

it be vdesired to lc'ck the doors 5 and 6.

y Fixed in the free end portion of the latch bar 16 is a rivet whosehead 19 projects .from the outer side surface of saidlatch `bar 16 ltoform afdetent,fand between said rivet and the slotted hole 17 isa holethrough which extends the shank 20 of locking member 21 that is providedwith a knob 22 and two lugs 23 and 24 which extend radially from saidlocking member 21.

The shank 2O of the locking member 21 is longer than the thickness ofthe latch bar 16 and its inner end is provided with a washer 25 that isfastened to said inner end by a screw 26; thus the locking mmber 20 maybe drawn outwardly for the distance limited by said washer 25 so that,when required, the locking member 20 may be rotated without causing thelugs 23 and 24 to engage with the rivet head 19 thereby to obstruct therotative movement of said locking member 20, as indicated in Fig.V 4.

If, however, the locking member 20 is locking member 20, while the l lug24 is' adapted to engage with the catching surface of said catch 12 inresponse to a contraclockwise rotative movement of said locking member20. VBut, such rotative movements can take place only Vwhen the lockingmember 20 is drawn outwardly to the point where the washer 25 willengage with the inner side surface of the latch bar 16, and, thereforein the operation of disposing the parts, as shown in Fig. 3, to lock thedoors 5 and 6 it is necessary, first, to close the door 6 and then toclose the door 5, whereupon the latch bar 16 may be swingingly moved toforce inwardly the curved end portion of the bar 3 until the catch 12projects through the slotted hole 17 for such distance that one of thelugs 23 and 24 can be moved to its lockingposition under said catch 12while the locking member 20 is drawn outwardly to its fullest extent,and when if said lugs as, for instance, the lug 23, is in its lockingengagement with the catch 12 then the pressure againstthe bar 16 isdiscontinued whereupon the force of the bar 8 will press the bar v16outwardly to the position shown in Fig. 2 so that the rivet head 19 willengage with the lug 24 to prevent further rotation of the Vlockingmember 20 until the latch bar 16 is again pressed inwardly.

' To unlock the doors the bar 16 is first pressed inwardly to permit thelocking member 20 to be drawn outwardly till it can be turned withoutbeing obstructed by the rivet head 19 whereupon the lug 23 may bedisengaged from thecatch 12 in an obvious manner to permit said latchbar 16 to swing outwardly from said doors 5 and 6.

side of the latch bar 16 in a position to en-V gage its other endportion with the outer surface of the door 5 when said latch bar 1 6 isin a position to lock the doors 5 andy 6;

said spring-like bar 28 thus taking the place of the bar 8 of Figs. '2,3 and 4 to perform the same function by the same mode of operation.

AIf my hasp fastener is to be used in con- 'nection with a single doorthen the bracket 15 is fastened tothe door frame of such single door inVthe same ymanner that it is fastened tothe door 6 of Figs. 2 and 4.

Obviously, `changes may be made in the forms, dimensions and arrangementof parts v of my invention without ydeparting 'from the spirit thereof.Y Y

What I claim is: A hasp fastener comprising a provided with Ya hinge onone of itsl end portions to adapt it to vbe hinged toa door frame, andprovided with two holes disposed to extend through its other endportion; a locking member provided with a Vcylindrical shank and aradially projecting locking'lug7 said shank being rotatably disposedwithin one of said holes and being adapted tol be moved inendwise'directions therein; adetent fixed on said latch bar and disposedtov adapt it to engage with said locking lug in response to a rotativemovement of said locking member when said locking lug is in engagementwith the adjacent side surface of said latchbar; a catch adapted toLproject through the otherl of said holes to make locking engagementvwith said locking lug; and a spring associatedl with said latch bar in aposition to adapt it to .exert a pressure against said latch bar whensaid locking lug is in engagementwith said catch.l Y v Y In witnesswhereof, I hereunto subscribe myname this 17th day' of .Ianuary'A D.,
